What's New in Spring Batch 4.2

The release of Spring Batch 4.2 mainly enhances the following improvements:

Use Micrometer to support batch metrics (batch metrics)

Support for reading / writing (reading/writing) data from Apache Kafka topics

Support for reading / writing (reading/writing) data from Apache Avro resources

Improved support documentation

Batch metrics using Micrometer

This release introduces how you can monitor your batch jobs by using Micrometer. By default, Spring Batch will collect relevant batch metrics (including job time, step time, read and write items, and other relevant information) and register these metrics with the spring.batch prefix (prefix) in the global metrics of Micrometer.

These metrics can be published to any monitoring system (monitoring system) that can support Micrometer.

For more details on this new feature, please refer to the Monitoring and metrics section.
